Brown and black coal are mostly used as a source of fuel for power stations. Burning the coal produces heat which is used to make steam, so the the coal is sometimes called thermal or steam coal. The steam spins turbines to generate electricity. In Australia in 2017 coal was used to produce about 60% of the nation's electricity requirements.

A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.

In thermal power plants, the heat energy obtained from the combustion of fuel (coal/natural gas/other carbon base fuel) is used to convert water into steam. The high temperature and pressure steam are used to rotate the turbine blade, turbine shaft is connected to generator. The generator converts the kinetic energy into electric energy.

Thermal power plant development started in 1866 when Werner von Siemens built the first dynamo for power generation. Years later in 1882, Thomas Edison developed the first central power station in New York [37]. In the first steam generators, the generated steam to drive the DC dynamos is either lowpressure saturated or slightly superheated.
